Can material objects be accelerated up to lightspeed?
5. A proton of mass m is accelerated up to a kinetic energy K and then collides with a stationary proton at rest. All that is left after the collision is a new particle of mass M. a. Write out the momentum and energy equations for the collision. b. What is the maximum mass M that can be created in this collision?
A material point that at instant t=0 is positioned at the origin is moving in a uniformly accelerated mode with acceleration a=-1,5 m/s^2. Find the expression for instantaneous velocity knowing that at t=4s the velocity is =15m/s. Also calculate the distance the material point covered in the first 5 s. Please use derivates and equations. answer is: v=21-1,5t. and s= 86,3 m
You are told that there are three rooms that are completely empty of material objects. One room is filled with a magnetic field, another is filled with an electric field and the third room has no electric or magnetic fields in it. Taking any simple equipment into the rooms with you, how can you tell which room is which? Explain exactly what you would do, and how you would know which is which?
How does the ratio of mass/ volume compare for different objects of the same material.
Two objects of different material have the same mass and temperature. When adding them equal amount of heat, the final temperature of each one can be different since they have different? Specific heat Density Expansion Coefficient Thermal conductivity Volume
Sometimes a person cannot clearly see objects close up or far away. To correct this type of vision, bifocals are often used. The top half of the lens is used to view distant objects and the bottom half of the lens is used to view objects close to the eye. A person can clearly see objects only if they are located between 36 cm and 160 cm away from her eyes. Bifocal lenses are used to correct her vision. What...
